MACHINE :F1313J TYING BOX-LAK BUNDLES;

To all whom may concern:

Bev it known that l, Enviar Gr. STAUDE, of Minneapolis, Hennepin county, Minnesota, have invented certain new' and useful lin provenients i Machines for Tying Box- Blank Bundles, of which the :following is a specification.

Boi; blanks, upon delivery from the box making machine, are folded and glued and stacked up in piles ci: a suitable number for convenience in handling and as they are removed from the stacker are tied up in bundles until suchtime as required forlill ing. Generally these bundlesare tied by hand, a laborious and tedious operation requiring the services of a number of at tendants, and the bundles mustbe carefully tied or the blanks will slip out and the package will be brokenfup.

The primary object of my invention, therefore, is to provide means for subjecting the packages of blanks to suitable pressure and tg, 'ng a cord around them, so that when the Lckage is released, the expansion of the blanks will tighten the cord and positively prevent anyr or' the blanks from slipping out of the package, even though they are thrown from place to' place in the store room.

My invention consists generally in a means for subjecting the package of blanks to suitable pressure in combination with an automatic tying mechanism for securing a cord around the bundle.

1n the accompanying drawings forming f part of this specification, Figure 1 is a top view of a machlne embodying my invention,k

position, Fig. 12 is a detaihsectional View,

showing the` drive shaft and pulley, and' the clutch in connection therewith.

ln the drawing, 2 represents a frame Awhereon the operating mechanism of the machine is mounted.

3 is a bracket supporting a shelf et upon which 'the packages of blanks are placed.

5 is a drive shaft having a driven pulley 6 operated from a suitable source of motive power, not shown, and running loose normally on said shaft, but rendered operative by means of a clutch mechanism of common construction, illustrated in Figs. 9 and 12,

and which I will now describein detail. A.

hub Gis secured on said shaft and has. a wing 7. pivoted at 8 thereon and normally held toward the center of said hubby means of spring 9. The wingf? has a square face 10 at one end and a seat 11. The pulley 6 has -antioriction rollers 12 thereon, adapted to engage the seat l1 and drive the pulley through said rollers. Normally, however, a dog 13, .pivoted at 14, engages the face 10 of rthe wing and forces it outwardly against the tension of its spring 'out of the path of the rollers 12, so that as the pulley revolves, normaliy, the shaft will be stationary. The dog 13 is normally held in' position to engage the face 10 by a spring 15. An arm 16 is connected with said dog and is adapted to enter a notch 17 provided in the lever 18, to which one end of the spring 15 is con-- nected to hold said lever in engagement with the arm 16' and against a stop pin 19. A

shaft 20 has a link 21 connecting it with theA lever 18 and a treadle 22 is mounted on said shaft and adapted to rock the shaft to move the lever 18 lengthwise and bring a cam surface 23 thereon into engagement with the pin 19 for thepurpose of raisingthe lever until it clears the arm ld, whereupon the dog 13 will assume the position shown in Fig. 10, releasing the wing and allowing one of the rollers on the pulley to engagev the surface l1` and drive the shaft. The lengthwise movement of the lever 18,'pulling onthe arm 16, will trip he pawl and release the wing 7 and eveni the operator keeps his foot et? the treadle the' pawlwillV nevertheless return to its locking position and stop the machine after the shaft has made onecomplete revolution. lt will make,

therefore, no'difference whether the operator keeps his foot on the treadle or removes it, the machine will stop after each complete revolution.

`A shaft `24 is'journaled inthe machine frame and carries a compressor arm-25,.

loosely mounted thereon. Said shaftalsb has a arm 26 secured thereon,f.proy1ded withantu-friction rollers27 and Y'havlng a hub with'lugs 28 thereontwhich projecten.

. .with the arm 26 and, is put lunder tension when the arm is forced down to return it and the compressor arm to their normal position. A cam 3l4 is mounted on the shaft 5 .and engages the roller 27 to operate the arm 26. The edge of this cam is soconstructe'd j as to cause-the compressor arm to be stationary at a predetermined point. in its stroke for a -suflicienttime to allow the tying of the knot in the cord that is passed around the bundle of blanks. This cord is contained in a can 32 and passes through a s uitable tension device, tothe hereinafterdescribed, and from thence through an eye 33 `on the compressor arm to the knotter 34.

This knotter is of any suitable construction 'and as it forms the subject matter of a separate application, .I will not attempt to illustrate or describeit in detail herein.

The tensiony device illustrated in Figs. 5 to 7 inclusive consists of an arm 35 pivoted on a stud 36 and'havin an upwardly extending arm 37 lprovide with an anti-friction wheel 38 that is engaged by a cam 39 on the shaft 5. A second arm 40 is mounted on the stud 36 and is adapted to enter a slot 41 provided in' the eye 42 in the arm 35. The arm 35 lfas a bracket 43 depending therefrom betweenwhich and the arm 40 a spring 44 is arranged."` A spring 4 5 normally resists downward movement of the armr 35 and a pin 46 is mounted on the frame in the path of the arm 40. The cord passes through an eye 42 and is gripped therein by the end of the arm 40. The engagement of the cam 39- with the anti-friction roller 38. will swing the arm 35 downwardly against the tension of its spring. This movement vwillrelieve thev pressure of thesprin 44 on the arm 40 and permit the cord to e pulled through the eye until a lsullicie'ntl length' has been obtained to wrap .aroundthe package. When the'y cam passeslthe roller, the arm 35 will return to its normal position, allowingr the spring 44 to force the arm 40 upwardly into engagement' with the pin 46 and temporarily gril; the cord', as indicated in Fig. 7

-4 is an .upright shaft :carrying a gear 48 ierating wheel @5l-aad@ 'ether :Screw lby aeuitb- By-the movement -o Lthiswheel the yoke-55,

which meshes with a pinion y49 on the shaft 5. The upper end of the shaft 47 has a bearing 50in the machine frame and carries a cam .5L-secured onthe shaft. A second cam 52 is splined tosaidfsfhaft and its hub has an 7 fanxiular lgrooy ei-53 receive the inwardly turnei'lend afa strap. 54-that is secured toa yoke 55, which 'iS verticallylmovable. on said shaft andjhas hlilsl rec-, eive.screws 58 and. 5.9; onifwhich is p vided'withan op- 7 withthe driving connection.

angdthe mechanism-carried thereby, may vbe` rar'sed or lowered Lto ada t the-machine for f,

box blanks ofdiierent sizes. A table 61 is carried by said yoke -and'has a slot 62 therein, whel'gein the compressor arm 25 is-adapted to oscillate, being limited in its movement in o 'f direction by a stop 63. Studs 64 and s 65 a e journaled 1n the-yoke 55 and in the upper portion of the machine `fra'meand carry arms 66'and 67 which are 4capable of vertical oscillation land are operated by means ofshort arms 68 .having anti-friction e rollers 69 to bear on the cams 5l and 52. The arm 66 is normally held in its 'raised por sition by the tension of a spring 70. The outer ends of the arms 66 and 67 are provided with fingers 71,'forming fixed stops, 9

said fingers being diagonally arranged and plrojecting into the path of the incoming box anks. vSaid `arms also carry adjustable stops 72 vmounted in the bearings 73 in the ends of the arms and secured therein b set screws 74. The stops 72 are capable o rotary and longitudinal adjustment intheir bearings and have ends turned substantially at right angles to the main ortions thereof'I and project into the path o the bundles of blanks as they are moved over the surface of the table 61 by the compressor arm. In fact, the adjustment of these stops with re.- spect -to the compressor arm determines the degree of'compression to which the bundles are subjected. The box blanks vary, of

course, in length and consequently the height ,of the .bundles will vary, b ut the operator, lby the simple manipulation of the wheel 60,

can raise or lower the table 61 and one set of the stops until the machine is adapted for the size of bundle to be compressed and tied. The movement of the arms 66 and 67 is so timed by the position of the cams 51 and 52, that they will be swung to the dotted ,line position, as shown in Fig. 8, when the proper degree of'compression has been obtained and the cord has been tied around the bundle. The package will then move back t6 the rear of thetable, as indicated in Fig."2,'l.nd While 2J another package is being compressed, the diagonally extending iin ers 71 will engage the bound package and old it in place.

l By. the simple adjustment of the stops in their bearngs, the degree of .compression i lilled.,
